HAMMER ATTACHMENT FOR ANVILS.

Specification of Letters Patent. Patented Aug 1'? 1915 Application filed January 25, 1915. Serial No. 4,278.

To all whom it may concern .Be it known that I, ASHTABULA Games, a citizen of the United States, residing at Westminster, in the county of Oconee and State of South Carolina, have invented certain new and useful Improvements in Hammer Attachments for Anvils, ofwhioh the following is a specification, reference being had to the accompanying drawings. 7 My invention relates to 1ron working, and particularly to means for operating a sledge hammer in j n n with anfa-nvilf'f The primary obj ect of my invention is the and at the same time horizontally toward the anvil'to thereby. alter not only the point of contact of the hammer with the anvil, but also shift the angle of inclination of the shank, and in this connection to provide means whereby the angle of the hammerface may be changed with relation. to the face of the anvil, either independently of the shifting of the hammer shank, as before stated, or coordinately therewith.

Still another object is to improve upon constructions of this character by simplifying the mechanism, rendering it more positivein its action and making it more fully under the control of the blacksmith, so that blows may be delivered with a greater or'less force and so that the head of the sledge hammer may be applied to suit the character of the work being done. f

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein- Figure 1 is aperspective view ofran anvil with my attachment, applied thereto; Fig. 2 is a fragmentary elevation, partly in section, of the sledge hammer supporting means, showing the manner inwhich it may be adjusted Fig; 3 is a fragmentary transverse section to show the means for adjusting the sledge hammer.

Referring to the drawings, 2 designates an anvil of the usual form and3 the anvil block upon which the anvil is mounted. As illustrated, in order to dispose the parts at all times in proper relation, the anvil blockis supported upon a base 4 and rigidly connected thereto in any suitable manner. The end of the base 4 opposite theend of the block is illustrated as formed with the upstanding supporting member 5.

Mounted upon the member 5 and extending up therefrom are the spaced standards 6, the upper portions offwhich arelongitudinally slotted as at 7. These standards are rigid and are held securely to the supporting member 5. Disposed between these standards is-a brace 8 which is securely connected with the standards in a manner which will be later stated, and which at its other end is. disposed between ears 9 proj ecting-"fromv the anvil block. The brace 8 is pivotally connected to the ears 9 by means of a transverse boltlO. Rigidly connected to the outer end of the brace 8 and extend ing up therefrom at right angles thereto are the hammer supporting members 11, preferably formed of angle iro n. These members 11 are disposed against the outer faces of the standards 6, and passing through the members 11, through the slots 7 in the standards 6, and through the outer end of the brace 8, is a bolt 12. One end'of thisbolt is provided with any suitable head and the other end isprovided with a clamping nut 13 having a handle whereby it may be readily turned. The brace 8 at its outer end is formed with a short longitudinal slot 14 through which the bolt 12' passes. The brace 8 is connected with the upper ends of the hammer supporting members 11 by means of diagonal braces 15 which are also preferably formed of angle iron.

Extending downward from the brace 8 and attached thereto in any suitable manner is a-bracket 16 braced by means of a diagonal brace 17, to the lower end of which bracket and brace is pivotally connected a lever 18. This lever extends nearly .to. the anvil block, and at its end adjacent the anvil block is provided with the oppositely disposed plates 19 forming extensions on the lever between which is pivoted a link 20 which passes upward and rearward through a slot 21 formed in the brace 8. Attached to the lever '18, and specifically on each side of =the plates 19, is a split ring or yoke 22,

attached to the yoke or ring 22 in any suitable manner.-

the ends of which are flanged as at 23 to bear againstthe 1 plates 19, a bolt or f like fastening device extending through the ends 7 of the yoke, and through these plates and the lever 18. The plates 19 at their forward ends are laterally bent as at 24, these later ally bent ends being riveted as at 25 to the yoke so as to brace the yoke rigidly and hold it in rigid alinement with the lever 18. These braces 24 of course do not touch the anvil block3, but are spaced therefrom sufficiently to permit the free movement of the lever 18. j

Disposed upon the ring 22 directly in line with the lever 18, is a treadle 26 which is Pivoted between the upper ends of the hammer supporting memberzll is the sledge hammer shank 27. This shank is pivoted upon a pivot pin or bolt 28 passing through the upper ends of the members 11, and this shank 27 extends rearward beyond this pivot pin as at 29.. A. clevis 30 is pivotally attached to this rearwardly projecting end 29,

and to this clevis is connected the helical spring 31, which atits lower end is connected to a bolt 31 extending through'the brace 8 at an angle thereto. This spring 31 is a contractile spring and acts to yieldingly hold the hammer shank in the position illustrated in dotted lines in Fig. 1, but will yield to permit the hammer shank to rotate in the direction of the arrow, Fig. 1, so as to cause ,a blow to be struck upon the anvil.

Thelink 20 at its upper end is pivotallyconnected to a collar 32, which collar is ad-i j ustable along the hammer shank, but is held clamped in any adjusted position thereon by means of the bolt 33 which passes through extensions ofthe collar and through the link 20. When this collar 32 is clamped upon the hammer shank, the link 20 has pivotal engagement with the plates 19 so that a pressure on the yoke by means of the treadle- '26 will cause the hammer shank to be pulled down. When the pressure on the treadle 26 is released the spring 31 will act to draw thehammer-shank upward in a manner obvious from the illustration. '7

Preferably the hammer shank 27 is made of wood reinforced by longitudinally extending side plates 34 on the rear side faces 7 of the hammer shank, these side plates being riveted or bolted to the shank.

The hammer head 35 is pivotally supporti ed by means of the pivot bolt 36 between the projecting ends of the laterally disposed strips 37 which are riveted to the freeendv of the hammer shank, and preferably the hammer head has projecting from its inside facea sector 38'whichis arcuately slotted as at 3.9, a bolt 40 passing through the strips 37 and through this arcuate slot. This bolt 40 is a clamping bolt and when set up will hold the hammer head in any desired angular relation to the hammer shank within the limits of the slot 39. r

The operationof my invention will be obvious.

Normally the spring 31 holds the hammer raised and the hammer shank in the position shown in dotted lines in Fig. '1 and the treadle 26 raised to the position'shown in dotted lines in Fig. 1.1 Upon a depression of the treadle 26 by the foot of the blacksmith the hammer will be drawn down and will strike the work supported upon the anvil.

The strength of the blow thus struck may of course be regulated by the amount. of force applied to the treadle. I have found in practice that this force may be so applied that all of the ordinary work of the hammer,

may be performed. The leverageexerted by the. lever 18 upon 1 the hammer may be changed by shifting the collar 32 along the hammer shank. In order to change the point of contact of thehammer with the: anvil so as; to cause the hammer tostrike any particular part ofthe anvil it is only necessary to release the clamping nut 13, V

sector 38; By this means the angle of the hannner with relation to the shank is read ily changed and then the hammer locked in its position.

It will be noted that in my attachment the hammer isnormally supported entirely away from over the face of the anvil thus permitting the anvil to be used. for other work and not in anyway interfering with the ordinary use of the anvil. It is furtheri to be noted that side strain is done away with by having the foot lever passed around the anvil block and puttingthe foot pedal on a line with the hammer. Furthermore, it will be noted thatthe spring 31 is in its dormant positionwhen the hammer is raised,

' or. nearly perpendicular. This allows the operator to start the hammer with very little strain uponthe spring 'and thus start the hammer with relatively small amount of effort. It further permits the operator to start either slowly or 'quickly, and thus either a light blow or a heavy blow can be secured. I a By adjusting the hammer 35 with relation to the hammer shank or handle thehammer Y may be set to strike the'work at "any desired angle, which is particularly useful; in scarfing iron for welding, or in drawing out plantation plows and sweeps. By the use of my device the blacksmith can trim a plow and hammer it out, and

weld wagontires or do any other welding and accomplish a large amount of other like work, while. at the same time his hands are free for properly manipulating the work 011 the anvil. He can also hold the work upon the anvil with one hand, wield a hammer with the other hand, and operate the hammer 35 by means of his foot, and infact in many casesdo the work better thanthe work can be done with a helper to'do the hammering. i

It is to be noted that in order to shift the hammer shank with relation to'the anvil so is valuable in many classes of work, as for instance, in operating upon a piece of iron ,which is transversely curved or has an angular surface. Furthermore, the angle of the face of the hammer head with relation to the anvil may be changed by rotating the hammer head upon the pivot 36 either independently of any upward and inward shifting of the hammer shank, or coordinately therewith, so that if it is not required that the hammer shall strike downward and toward the member 5 or rather if it be not re uired that the face of the hammer, when it strikes the anvil, shall be relatively upward and toward the front of the machine, the hammer 7 may be so adjusted that it will strike fiat upon the face of the anvil even though the hammer strikes upon the extreme rear face of the anvil.

My invention is simple, is very effective in practice, andmay be easily removed or disassembled when it is not desired to be used, and may be very cheaply made.
